Unless a customer shovels a lot of money our way, SSIO won't get any attention
until after X86 ships.

I *think* that what shipped as part of the SSIO project was a very limited
prototype that was limited to a single node with no cluster wide locking semantics,
so it's not a surprise if something fundamental is not fully implemented.
